Specification forming part of Letters PatentNo. 36.073, dated August 5,1862.'

To all whom it may concern:

Be it4 known that I, Cnniunnl` M. CLARK, of the city of Cincinnati, inthe county of Hamilton and State of Ohio, have invented a new andusefullmprovemeut in Broadcast-Sowers;

and I hereby declare 4that the following is a full, clear, and exactvdescription of the same,

' reference being had t0 the accompanying d rawings and letters ofreference marked thereon,

which form part of this specification.

My invention has reference tothe method of distributing or scatteringthe seed 5 and it consists of a hopper or receptablefrom which the seedis blown by a'revolviug fan through a series of diverging ducts, thewhole being coustructed in such a manner and of'such a size as `to beconveniently carried and operated by a man or boy.` 3`

' In order that others duly skilled may be enabled to understand andconstruct and use my improved sewer, I shall proceed to describe thesainen-d etail.,-V

In the accompanying drawings, Figure 1 is a photograph showing amancarrying and operating the implement. Fig: 2 isa vertical section of theimplement .cut bya plane at right angles to axis of fan-blower. Fig. 3is a horizontal section through the diverging'seeddets.

Like letters of reference designate like parts in all the drawings.y v

A is the hopper'or'seed-reservoir. It may be constructed of wood,4tinued iron plate, or.

-of`ther suitable materiahand of a shape convenient for being carriediufront of thebody by the operator. The bottom a of said hopper is madeslanting downward. and forwardand joins the door b of seed-ducts, Fig.2. In front,

and rat the lower part of hopper, a cylindrical case of sheet metal, B,is fixed, part ofsaid case forming the lower portion of front wall of nthe opening O at'bottom of hopper, and thus control the delivery' ofseed therefrom into ducts D.

Within the cylindrical case B a fan, F, is made to 'revolve-bymeansofthe drivingwheel W, which wheel is journaled ona prolongation.

of the bar W', on which the fan-blower Fis journaled, and isprovidedwith a hand-winch,- H. The periphery of the driving-wheel vW is made tocome in close contact Awith periphery of a small pulley, I, on end ofaxle J of fan, a l

band of vulcanized caoutchouc or other elastic material beingstretchedaround said pulley I in order to make the` contact more complete.

On the rotation of the driving-wheelWby the operator the fan'is rapidlyset in motion by the frictiou'between the two surfaces or peripheries bythe rapid rotation of the fan F.

lThe seed ,admitted from the hopper A are blown through the divergingducts D.

The ducts, of which there may be any num-- ber, are shown in planonFig'. 3 as being curved outward something in the manner of a fan. Theseed, in beingpropelled through these ducts f lby the' blast fromfam'takethedirection-of'the ducts, and thus diverge more and more widelyf in proportion tothe distance they reach before falling to the ground.By means of thehinged valve S the rate ofdelivery of seed to the fan,may

be regulated with thegreatest nicety, and when it is so requiredjthecommunication' between the hopper and the fan-case may be entirelclosed, as showuin black lines, Fig. 2, l

rlhe operation of my invention, after, what has beensaid, may beexplained in afew words.

vThe implement, being suspended by a strap 'i passing around the neckofthe operator, is carried in front, as represented in Fig. 1, and, the

hopper or canvas bag being filled with seed, Y

valve E isset to the required opening'and the rotation of wheelWcommenced, the fan F being rapidly rotated., The current of air whichis generated forces the seed out through the seedducts D iu continuonsdiverging streams, thus distributingthe seed regularly and evenly, andvrequiring-but little labor and attention on the 4part ot'theoperator.

It should here be particularly observed that the arrangement andoperation of this machine is such that theseed i's impelled outward, notonly by the current ot' air, but that the blades of the fan alsoencounter a portion of the grains and impart an additional force tothem, so that a considerably greater `breadth of ground is reached bytheseed than would be reached if E and screw A the seed were impelled bytheair only. In

-this particular respect, as well as in many It should b e mentionedthat this apparatus e may be employed with advantage in projectinge`sand upon the freshly-paintedv surface of walls. The force with whichthe sand is proiected causes it to penetrate 'thoroughly and leave aheavy uniform coating of sand well in` Y corporated with the paint.

Shouldit be desired to connect this machine with a vehicle to be drawnby a team, thus making apower-soivenitmaybe considerably enlarged,,andthe fanmay be operated by'a band or gearing connecting it with arevolving pulley or wheel attached'to some of the' running parts of thevehiclein any convenient manner, such as are in common use for accomnclaimth'e use of thev fan-blast separately-for v the purpose hereindescribed.

I .elaim- Projecting the seed from the cylindrical case B, in which thefan revolves7 by means of the tan-blast, in combination with the'impactof 'theblades of the fau, substantially as described'.
